Full speed USB to RS232 bridge

■

The demonstration board works as a bridge 
between a standard USB port and a classical 
serial COM port

■

The standard CDC class of USB is 
implemented and emulates COM port 
functionality to a standard USB port

■

The demonstration board implements RS232 
full hardware flow control using RTS and CTS

■

The STM32 medium density line device 
performs the communication task (bridge) 
between the USB and RS232 (UART)

■

A standard DB9 connector (female) is used for 
RS232 and therefore the user can directly 
connect this demonstration board to the PC

■

The unit is bus-powered (this means it takes 
power from the USB bus)

■

RoHS compliant

The STEVAL-PCC015V1 demonstration board is 
an easy and compact solution in order to make a 
bridge between a standard USB port and a 
standard serial COM port. In modern PCs, USB is 
the standard communication port for almost all 
peripherals. However many industrial software 
applications and old equipment still use the 
classic COM port (UART).                                    
The STEVAL-PCC015V1 demonstration board 
provides a simple solution to overcome this 
problem.
